Presentation Transcript

  1. Le Chatelier’s Principle “If a system in equilibrium is subjected to a stress, a change that will offset the stress will occur in the system.”

  2. Le Chatelier’s Principle “If a ‘stress’ is applied to a system in equilibrium, the equilibrium condition is upset; a net reaction occurs in that direction which tends to relieve the ‘stress,’ and a new equilibrium is obtained.”

  3. In equilibrium

  4. Addition to the equilibrium

  5. Out of Equilibrium

  6. Return to equilibrium Addition to Equilibrium state

  7. New Change

  8. New Equilibrium

  9. Bicarbonate & Carbonic Acid H+ HCO3- H2CO3

  10. New Equilibrium H+ HCO3- H2CO3

  11. H2O + CO2 H+ + HCO3-

  12. H2O + CO2 H+ + HCO3- In ECF around cells

  13. H2O + CO2 H+ + HCO3- high high In ECF around cells

  14. H2O + CO2 H+ + HCO3- New equilibrium in ECF/ blood

  15. H2O + CO2 H+ + HCO3- Moderate levels moderate levels

  16. H2O + CO2 H+ + HCO3- Breathe out In the lungs

  17. H2O + CO2 H+ + HCO3- In the lungs Equilibrium correcting itself

  18. H2O + CO2 H+ + HCO3- In the lungs

  19. H2O + CO2 H+ + HCO3- Breathe out In the lungs

  20. H2O + CO2 H+ + HCO3- Equilibrium correcting itself

  21. H2O + CO2 H+ + HCO3- New Equilibrium in the lungs and ECF

  22. H2O + CO2 H+ + HCO3- In the blood again
